Yup. And you're not the only ones. My old club back in Chicago, running 
3A as K9OR, regularly places in the top of their class. They've been all 
K3 for quite a few years.

I'm part of a team that sets up 3-4 stations in a rare county for the 
California QSO Party. We carefully locate antennas to minimize 
interstation interference, with a goal of CW and SSB on the same bands. 
We've ALWAYS run K3s with 600W power amps into tribanders separated by 
about 250 ft, and 80/40 dipoles with about 400 ft separation and arrayed 
colinearly. This year (Oct 3-4) will be our first year with new synth 
boards. When we have enough of them, the amps are all KPA500s. One year 
I brought a used ACOM 1010 I had acquired thinking that being a tube 
amp, it might be cleaner. Turns out it's got a bit more IMD than the P3.
